If your business accepts credit cards, then you are at risk for potential liability in the event of a data breach. You need to be aware of the importance of keeping your customers' personal information secure. Many businesses accepting credit cards are unaware of the PCI standards and may only learn about them when a data breach occurs. While there may be many causes for a data breach beyond the control of the merchant, being aware of the PCI standards and appropriately implementing them in your business is part of the cost of doing business today.
